Don’t have an ipad, but why the extra expense on another gadget?
Do you have an android phone already? Why not use that?
If you don’t, buy a prepaid one and use that for the truck phone # and processing square.
Boost mobile is $50 a month, phone around $179….
I just bought an at&t phone, it was $125, it gets the job done, the service is more but it’s the only thing that works where I moved to.
